\[ \begin{array}{l} {u_{i} \leftarrow\left[u_{i}-\gamma_{t}\left(\lambda-\left(y_{t}-w^{\top} \Phi\left(x_{t}\right)\right) \Phi_{i}\left(x_{t}\right)\right)\right]_{+}} \\ {v_{i} \leftarrow\left[v_{i}-\gamma_{t}\left(\lambda+\left(y_{t}-w_{t}^{\top} \Phi\left(x_{t}\right)\right) \Phi_{i}\left(x_{t}\right)\right)\right]_{+}} \end{array} \]

\[ f^{\prime}\left(x_{0}\right)=\lim _{\Delta x \rightarrow 0} \frac{f\left(x_{0}+\Delta x\right)-f\left(x_{0}\right)}{\Delta x} \]

\[\begin{equation} w \leftarrow w-\gamma_{t}\left\{\begin{array}{ll} {\lambda w} & {\text { if } y_{t} w^{\top} \Phi\left(x_{t}\right)>1} \\ {\lambda w-y_{t} \Phi\left(x_{t}\right)} & {\text { otherwise }} \end{array}\right. \end{equation}\]
